This invention relates to a method of decoration, ornamentation orpainting that is carried out without the use of a pen, brush or pencil,and to secure in a simple way effects resembling those secured in oilpainting by means of a brush, but without necessarily involving theskill of an artist.

According to theinvention, paint or colour is applied by hand. by meansof stamps -of indiarrubber or other similar yielding substance, to giveim ressions of leaves, flowers, flower-sprays, ranches, trees, figuresor any other details for making up a picture or for the decoration orornamen tation of an article or surface. For this purpose the printingsurfaces of. the stamps used are provided with recesses or pocketswithin which the paint or colour to be applied is received, and so; thatthe paint or colour from the recesses or pockets is applied upon thesurface upon whichthe impressionis to be made, whereby the paint orcolour may be applied more densely at those positions. than at otherpositions of. contact of the printing surface with the surface uponwhich the impression is to be made. The paint or colour may be appliedin greater or less density or quantity according to the pressure imposedin making (it) the impression and tothe form of the printing face. Thusthe recesses or ockets are of such form and disposition tiat onimpression the greater amount or density of colour will beappliedatthose positions at which the recesses or pockets are applied. Thus inthe use of stampsffor the representa tion of flowers or leaves forexample the greater amount or density of colour: may be applied at thepositions between the petals or leaves in such manner that the, actualform of the stale or; leaves isindicated by the density of colour andform of the denser deposits in positions between. Similarly theprintings'urfaces may be formed with slight or shallow recesses inparticular positions according to the light and shade effects desired]and the form and graduations of density of, colour deposited adjacentthe po sitions at which high light and deep shadow are required, itbeing understood that the dis ersion'of the colour or paint effected uner pressure when taking it up and when applying it inimpression may bevaried according to the pressure applied, and that varying graduationsof lightand shade may be secured by the amount or density of the colourtaken up. Thus varyingv effects are secured by variation in the pressureapplied in taking up the colour or paint as well as in the pressureapplied in impression. The depth and shape of the slight or shallowcavities in the printing surface and of the recesses or pocketsreferredto are sodetermined that the subject. is represented in de tail by thedeposit ofpaint or colour from posited and spread, or have been mixedin,

order'to produce particular tints or mixtures of colours that are to beapplied, care being taken that by reason of its more or less uniformdistribution no more of the palntor colour is taken up than is requiredin the impression, and that the stamp is applied with such a degree ofpressure as is necessary according to the character of the impression tobe made. I

The stamp having'the paint or colour thus applied on its printing face,is then impressed upon the surface to be painted,

decorated or ornamented, and by thus impresslng the stamp witha-pressure variable accordlng to the efi'ects to be secured, the

paint or colour is pressed. out of the re-.

cesses; or pockets and'from the very shallow cavities on the printing,face of. the stamp, and thus the paint or colour may be more or lessirregularly distributed or in a manner resembling thatin which colour isapplied in oil painting by means of a brush.

It-will be-understood thatthe printing surface may be variously formedto secure the effects aimed at; for example, in providing a.

stampfor the representation of a leaf ora number of leaves on a branch,insteadofi the printing surface being. fiat, it is provided with slightor shallow cavities following the conformation of the surface of. therespective leaves to be represented, andlwithrecesses or pocketsbetween, so that on pressurebeing applied to the stamp on its impressionupon the surface to be painted, the paint or colour is pressed out ofthe very slight or shallow cavities on the printing surface and out ofthe recesses or pockets which yield in the impression distinct lines ormasses of paint or colour. These lines or masses of paint or colour arealso applied in impression beyond the position of the edges of the leafor leaves or other details, whereby lines of paint or colour are thereapplied by reason of its expulsion at the edges referred to. By suchmeans the mint or colour is irregularly applied, and particular effectssecured according to the pressure applied.

Or again, the printing face of the stamps map be provided with slightprojections, ridges or other parts in relief between the pockets orrecesses and such parts in relief in the case of a leaf or other object:represented may follow its formation or its outer edge so that thus atthe positions at which these parts in relief are applied on the surfaceto be impressed, there is a minimum of paint or colour deposited and amaximum in positions beside such parts in relief.

The stamps for the representation of flowers, branches, figures, andother details may be similarly provided, and the printing surfacesformed with slight or shallow cavities therein or as irregular surfacesin such maliner that the colour is unevenly distributed in order tosecure the effects aimed at. Thus the paintor colour may be applied invarying amount or density at positions in shade and high light accordingto the pressures imposed in taking up the colour and in applying it.

Thus the matrices from which the stamps or printing surfaces areproduced may be engraved so that particular effects may be secured onimpression according to the skill of the engraver or designer, but theeffects aimed at according to the invention, may also be realizedespecially where the objects are small, in any convenient way involvingrecesses or pockets or other irregular formation of the printingsurface, which may more or less conform to the characteristics orfeatures of the detail or group of details represented.

According to the invention moreover the paints or colours used havevarnish incorporated with them or a substance or substances havingsimilar characteristics, thus oil colours usually employed in oilpainting may be used, with the addition of a propor tion of varnish, orprinters colours or inks in which a proportion of varnish is alreadyincorporated may instead be used; and the paints or colours may be putup in collapsible tubes and may be applied on to a palette or othercolour distributing surface on which the colours may be spread or bemixed in order to produce the articular mixture or tints desired.

Thus in the decoration of articles such as vases, bowls or other similargoods with a spray of flowers, a stamp is used to give an impression ina suitable colour of a branch or branches; a stamp may then be used togive an impression in suitable positions and colour of a spray or spraysof leaves applied on the b 'anches and a stamp may then be used to givein suitable colours the impression of a flower in determined positionswith reference to the branches and leaves. The colours employed andpositions at which impressions are made may be determined by the choiceor skill of the individual, or may be indicated in properly executedexamples of decoration, ornamentation or pictures that may have beenreproduced from specimens of the method of the invention.

Thus for carrying out the method of the invention, examples of efi'cctsproduced and of pictures, decoration or ornamentation involving a widevariety of details may be putup within the receptacles containing a setof the stamps required according to the subject and colours, togetherwith a palette or colour distributing surface on which the colours maybe spread for application upon the stamps.

Such a method of decoration. ornamentation or painting may be used forart teaching, and for decorating or ornamcnting a wide variety ofarticles of manufacture, it being possible to provide stamps and coloursin sets for the representation of particular details of decoration,ornamentation or painting.

The invention comprises the use of stamps made of an elastic substanceother than rubber.

The invention is particularly applicable in the decoration orornamentation of silk or other fabrics and other goods that requirewashing or cleaning-the colour applied being incorporated with varnish.

The stamps may be conveniently provided in a form resembling pencils ofwood and they may be provided of a uniform diameter or their bases maybe enlarged and shaped according to the form of the printing surfacemounted at their lower ends and provided as a layer of india-rubber orother suitable elastic substance which may be of a thickness of say f thor @th of an inch or more. The india-rubber is provided on its lowerface as a printing surface by moulding or by engraving or by othermeans. The stamps may, however, take any other form, for example, aholder may be employed in the manner of spring pincers which are adaptedto engage the rubber stamps by the provision of an extension on the topfat-e adapted to be engaged by the pincers, the form of the pincersbeing such that they may serve to engage the india-rubber stamp andapply pressure upon it for the purpose of hit) taking up colour and forimpression. It will, however, be understood that no limitation isimposed to the form of the stamps used. a

The manner in which the invention 'is carried into effect is illustratedin the accompanying drawings inwhich Figures 1, 2 and 3 are enlargedviews showing examples of stamps provided for carryinoout th method ofthe invention.
